For a continuous random variable X, P(20 ≤ X ≤ 40) = 0.15 and P(X > 40) = 0.16. Calculate the following probabilities. (Leave
yan [13]

Answer:

For a continuous random variable X, P(20 ≤ X ≤ 40) = 0.15 and P(X > 40) = 0.16.

Step-by-step explanation:

Here, P(x > 40) = 0.16

a). P(x < 40) = 1 - P(x > 40)

                   =  1 - 0.16

                    = 0.84

b). P(x < 20) = 1 - P(x\geq 20)

                    = 1 - {P(20 ≤ X ≤ 40) + P(X > 40)}

                    = 1 - (0.15 + 0.16 )  

                    = 1 - 0.31

                    = 0. 69

c). P(x = 40) = 0; The probability that a continuous variable assume a particular value is zero.

How to solve, -1.2x - 6.5x less than or equal to 2.3x + 5
Hitman42 [59]

-1.2x - 6.5x ≤ 2.3x + 5

-7.7x ≤ 2.3x + 5

≤ 10x + 5

-5 ≤ 10x

-1/2 ≤ x

x ≥ -1/2

in a round robin tennis tournament involving 7 players, each player will play every other player twice. How many total matches w
baherus [9]
Total number of ways to make a pair:

The first player can be any one of 7 .  For each of those . . .
The opponent can be any one of the remaining 6 .

Total ways to make a pair  =  7 x 6 = 42 ways .

BUT ... every pair can be made in two ways ...  A vs B  or  B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.

If every pair plays 2 matches, then  (21 x 2) = <em><u>42 total matches</u></em> will be played.


Now, is that an elegant solution or what !
